Most adolescents suffer from Gender confusion

Seven chimpanzees of different ages and sexes living in the Primate Research Institute at Kyoto University were part of the experiment. They sat in a booth housing a computer-based touchscreen and were trained to choose the stronger of two options (based on the rules of the game) they saw on screen. They first learnt the paper-rock sequence, then the rock-scissors one and finally the scissors-paper combination. Once they knew how the pairs fitted together, all the different pairs were randomly presented to them on screen. Five of the seven chimpanzees completed the training after an average of 307 sessions.

The findings show that chimpanzees can learn the circular pattern at the heart of the game. However, it took them significantly longer to learn the third scissors-paper pair than it did to grasp the others, which indicates that they had difficulty finalizing the circular nature of the pattern.

The research team then also taught the game to 38 preschool children to compare the learning process of chimpanzees with that of humans aged three to six. The children had little difficulty grasping the game, and on average did so within five sessions. Their performance was, however, subject to age. The older the children were, the more accurate they became when all three pairs were randomly presented to them. Participants older than 50 months (about four years) played the game with more skill rather than luck.

“This suggests that children acquire the ability to learn a circular relationship and to solve a transverse patterning problem around the age of four years,” says Gao. “The chimpanzees’ performance during the mixed-pair sessions was similar to that of four-year-old children,” adds Gao, who hopes the findings will inspire future studies into how age and sex influence the ability of members of various species to learn circular relationships.

much has been written about the gender confusion during early adolescence but biology and evolution proves all mammals have only 2 : male and female

The mammal Homo Sapiens has adopted the psychological construct there could be a rainbow of genders. Which science did prove long time ago has shown that the physical build of the brain determines gender
